CARHBRKE.

SPECIPICATION forming part of Letters Patent No. 388,262, dated August 21, 1888.

Application tiled May 9. 1888. Serial No. 273.294. (No model.)

To all whom it may cancel-n.-

Be it known that I, JAMES J. CoTEs, a citizen of the United States. residing at Moberly, in the county of Randolph and State of Missouri, have invented certain new and useful Improvements in Car-Brakes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencc being` had to the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specitication.

This invention relates to car-brakes, and has for its object to devise a means for automatically applying the brakes by the slowing up of the train.

The improvenicnt consists in having the tender of the engine provided with a movable draw-hcad which is held in position by a sliding block and with fixed push-bars, and in having the cars provided with sliding :frames or bars which extend the whole length of the car and have their ends about flush with the ends of the draw-bars, and in having connections interposed between the brake-bars and the said frames or bars for transmitting motion from them to the said brake-bars for applying the brakes when the said frames are actuated.

The improvement further consists in the peculiar construction and combination of parts, which hereinafter will be more fully described and claiined, and shown in the annexed drawings, in which- Figure 1 is a top plan View of a pair of trucks embodying my invention, showing the sliding block drawn back; Fig. 2, abottom plan view, parts being broken away, of the trucks, showi ng the block in position back of the drawbar; Fig. 3, a vertical section on the line XX of Fig. 1; Fig. 4, a detail perspcctive view showing the means for Operating the block; and Fig. 5, a detail perspective view, parts being broken away, of the frame or bars for operating the brake-levers.

The truck A of the tender is provided with the draw-head a, which is adapted to slide in, being held out or in a fixed position by, the block B, which slides in between the rear end of the draw-head and the cross bar or sill a'. The block B works in the space between the sill c', the bar az, parallel with the bar a', and the cross-bar ca, which unites the bars c' and a? and supports the block B, and is pivotally connected with the end of helever O, that eX- tends lengthwise of the truck, and has the hand-lever O' applied to its other end and eX- tended within convenient reach of the engiueer or fircman to be operated for moving the block B in or out, as may be desircd. The push-bars b oue on each side ofthe drawhead-have their ends tlnsh with the end of the said draw-bar when the latteris projected, and are adapted to bear against the ends of the frame or sliding bars D ou the car-truck E.

It is proposed to construct all the car-trucks substantially alike; hcnce a description of one will suffice for all. The bars I) extend from one end of the car to the other and have their ends about flush with the ends of the draw-heads e at the ends ofthe car-truck. The brake-bars F and G, extending from one side to the other side of the car and having brakeshoes at their ends, are connected niidway of their ends with each other by the rod f and the lever g. The leverg extends vertically, and is pivoted near its lower end to the brakebar G and at its lower end to the rod f. By pushing the longer end of the lever-g in, the brake-bars F and G will be brought together and the brakes will be applicd, and by pushing the lever out the brakes will be liberated.

The frame or sliding` bars are provided at one end with the cross-bar or stop d, which is adapted to strike the lever when the said bars D are moved in one direction and pnsh it in and apply the brakes, and at the other end with the vertical extension or stop d', which is adapted to strike the lever H when the said bars are moved in the opposite direction, and, through the rod I and lever J, move the lever in and apply the brakes. rI`l1us it Will be seen that the brakes can be applied whichever way the cars are nioving and whichcver direction the bars D are niovcd. In one direction the bars D, through the stop d, act directly on the lever g. In the opposite direction the bars D act indirectly on the lever g through the lever II, the rod I, and the lever J.

The ends of the bars D are flanged to insure the abutting` of the ends of the bars of two cars, and the bars are held in a normal position by IOO the springs K, mounted on the rods and held between the end sills of the truck and the collars or stops on the said bars.

When the cars are coupled together, the ends of the push-bars b on the tender will come opposite the ends of the bars D on the car coupled thereto, and the'ends of the bars D of each car in the train will come opposite each other. When the block B is slid from behind the drawbar a and the engine is slowed up, the drawbar a Will move in and the push-bars b Will bear against the'bars D and move them in, and the push-bars D will move the corresponding bars of the next car in, and so on throughout the train, causing an application of thebrakes, as will be readily understood. When the cars are draWn forward, the springs K will return the bars D to their normal position, and the drawhead a, being relieved from any external pressure, will be pushed out by the spring L, which is located in a slot in the said drawhead and confined between the front end of the slot and the cross bar Z, extending through the said slot and secured at its ends in the frame of the truck. When the cars are run together, the spring L is compressed, and When the cars separate the said spring L will push the draw-baraout sufiiciently far to allow the block B to be inserted behind the said draW-head, as will be readil;r comprehended.

Having thus described my invention, what I elaim, and desire to secure by Letters Patent, is-

1. The combination, with the' trucks A and E and the sliding bars D on the truck E, for actuating the brakes, of the sliding draw-bar a, the movable block B, and the push-bars b, substantially as and for the purpose described. 2. The combination, With the trucks A and E and the s1iding bars D on the truck E, adapted to have connection with the brakes, of the sliding draw-bar a, the push-bars b, the block B, the horizontal lever O, and the vertical lever O', extending Within convenient reach of the engi-neer,substantially as and for. the purpose described. i

3. The combination, with the truck, the lever g, connected with the brake-bars, and the sliding bars D, having the stop d', of the lever H, the rod I, and the lever J, substantially as and for the purpose described.

4. The combination, with the car-truck, the lever g, connccted with the brake-bars, and the sliding bars having the stops d and d', of the lever H, the rod I, and the lever J, substantially as and for the purpose speeified.

5. The combination, with the truck A, the sliding draw-bar a, the movable block B, and the push-bars b, of the truck E, the sliding bars D, extending from one end to the other of the truck and having the stops d and d', the springs K, for holding the bars D ina normal position, the brake-bars, the rods, and the lever g, connecting the brakebars, the lever H, the rod I, and the lever J, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
